I have been pondering this cheap exhaust mod for a while now. I basically cut off the center muffler (resonator) and put in a straight pipe.

I went to Canadian tire and picked up a 2.5" pipe 18" long and two clamps ($15). I then removed the center exhaust section and put on the work table. I cut close to the weld as possible, this made the removed section 16 1/2". Leaving me with about 3/4" overlap on new pipe per side. I put on the new pipe and clamped it up nice a tight. I then put exhaust section back under car to test the fit. I then cleaned the new section from dirt and grease and sprayed it with a few coats of BBQ paint (high heat) I had sitting around. I then bolted it back on.

Moment of truth as there was no turning back. Turn on the car. She sounds a LOT sportier.:p Has louder, low, deep, tone at idle but nothing annoying loud. Took it for a drive and made me smile. I love it. And the great thing is it's nothing annoying on the highway (you can hardly hear it). :D

I wish I would have done this years ago. Maybe I'll get a proper exhaust when this one rusts off but for $15....sounds good to me. Hope this helps a few people on a budget exhaust.

Pics below are of inside of resonator and the straight pipe on the car.

So does the straight pipe go to the back of the car? Or is it just dumping after the resonator?

Looks like fun. :)

yeah the stock resator is the only muffler i am using right now (http://www.saabcentral.com/forums/showthread.php?t=51485) and it sounds nice, but it seems to getting lounder and lounder, and i dont really like that much attention.... so i might be sticking the Saab Sport back on.
But very nice, i dont think i have herd of anyone doing this before.

Yeah one thing i have learned that if you want to do something, but you think about it too much, then it will proably turn out the same, but just take twice as long.

Viggen owners might try using a piece of pipe instead of either the muffler or resonator. However, there won't be any power gain on the Viggen because both the stock muffler and resonator are straight-through designs. :confused:

Honestly, if I had a 900 SET I'd have a pipe and exhaust tip put in the place of the stock muffer and just use the resonator only. The catalysts and resonator muffler more than you'd expect. But then ... I like loud exhausts. :D

Still ... a more agressive sound is just a piece of stainless pipe away. ;)
